ABSTRACT:
A ladle port assembly having a longer use life than a conventional porous plug includes an inner refractory member constructed from a high-fired alumina-containing refractory material, a middle refractory member surrounding the inner member and also constructed from a high-fired alumina-containing refractory material, a plurality of channel openings at an interface between the inner and middle refractory members, an outer refractory member surrounding the middle member, and a steel housing which contains the three refractory members. The high-firing of the inner and middle members increases their durability and hardness, reduces wear during use, and reduces the clogging of the channel openings which, in conventional porous plugs, has been caused by erosion and other forms of wear.
